Thanks Paul, as there were probably new LF records from the Lichen Ireland project years I’ll ask Janet about that, and I’ll get the Muellerella solenopsorae specimen in the post to you Monday or Tuesday. Going back to the Nagoya Protocol – Ireland ratified it in 2022/23 but did Kew have any advice on what the position is for collections after that date? Its of particular concern as I’m moving back next year
Thanks Paul – I’m getting rather good at pretending I didn’t find things (though some do get kept if enough survives my investigations)! Related subject but different question – do you know if there’s an updated list of Irish lichenicolous fungi since the one Howard Fox produced in 2001?
Hi Paul, I just tried accessing the new site by googling fungibi.info. but “Firefox prevented this page from automatically redirecting to another page” with fungidb.org/fungidb/. Is this just my Firefox settings? Thank you Paul and yes, one for Brian – and fortunately for once there’s a reasonable amount of the specimen left! Yes, I was surprised at the lack of records as it appeared to be abundant on some of the Collema on my drive! Thanks Neil for your reply and for checking your specimen – I’ve got a little bit of mine left so I’ll see if I can find any apothecia Thank you for your reply Alan, and my apologies as having checked my notes and photographs again I think was mistaken in saying that the gravestone was limestone. Your suggestion of Rehmia postuma (Rhizocarpon postumum) is interesting – I’ll record it as R. reductum sens lat but add your comment in the notes
Probably a very wild guess but might it be something like Lecanidion atratum? Thank you both for your replies and suggestions – but I really should have learnt by now not to attempt to identify slightly odd-looking crustose species from photographs! I’ll try and refind them when I’ve chemicals with me, and collect specimens to examine more closely
Thanks Neil, but no, as far as I could see they weren’t lichenicolous and are now in the post with the others Thanks again Neil, that’s an interesting possibility that two species could be present – though I’d discounted Arthothelium lirellans because of its spores – 17-27(-30) × 8-12 μm, muriform with (4-) 5-8 transverse septa? The location was originally upland fields with scrubby salix until my son’s mother-in-law started planting trees there about 30 years ago, rather than what I’d describe as a ‘proper’ high quality Irish site.
If you could email or message me with your address I’ll get them in the post to you in the next few days
Thanks for the quick reply Neil, and you’ve mentioned the same species I considered but also dismissed! Looking at my other micrographs again many of the spores from the first specimen had apical cells that looked to be developing /possibly developing additional septa – and there seemed to be very little trentepohlia present. The spores were slightly smaller, 13-16 x 5-6.
In the second specimen there was abundant trentepohlia but none of the apical cells were showing any sign of additional septation, though many spores still in the asci’s appeared brownish-green and possibly over-mature. Spores slightly larger, the largest 20 x 8.
I think when I measured the spores in the second specimen I discounted Reichlingia anombrophila, partly because of spore size and septation (2 to occasionally 4-septate) but also because of the LGBI3 habitat description:
Quote:On dry shaded, usually rough bark, towards the bases of old trees (esp. Quercus), more rarely on smooth bark(Betula, Corylus, Sorbus), in old woodland and parkland
I’ve retained both bits of Holly twig so I could send them to you or Brian for a more thorough examination?
(I’ve also got a couple small Arthonia “phaeographidicola” specimens if they’d be of interest?)
Thank you Neil – I thought there was a good chance it was but didn’t want to be too optimistic! I’m slowly going through the other twigs from that site and have found two more tiny bits – when I get to the end shall I send them to you as Brian was suggesting DNA sequencing?
Thanks Maxine – I really don’t like basidiomycete innards! I’ve very occasionally managed to find basidia in Tremella galls on Ramalina but I think that’s more by luck Thanks Neil, yes on U. cornuta sens. lat but as it looks like it would potentially be new for Ireland i wasn’t sure if the lack of a specimen (or at least basidia micrographs) might be a problem -
